< Topic >It is possible and to handle easily by human strength, it loads lightly in the freight vehicle and it offers the tree planting pruning job device which can do pruning job cheaply.SolutionsIt possesses the structure which can exchange job machine 17 length of arm 14 easily structure and arm 14 of variable possible arm 14 the adjustment device and the arm 14 whose is unrestrictedly expansion and contraction possible inside the range of specified length according to structure and the job contents whose is unrestrictedly time motion possible inside the range of specified angle by human strength. With this structure, as you do not use power, assure the light weight conversion of arm, 14 in the freight vehicle make lightly loading possible to price it converted low.< Choice figure >Drawing 1【課題】人力で容易に取り扱うことが可能であり軽貨物車両に積載して剪定作業が行える植樹剪定作業装置を安価に提供する。【解決手段】アーム部14の長さを人力で容易に可変可能なアーム部14の構造とアーム部14を所定の長さの範囲内で自在に伸縮が可能な調整手段とアーム部14が所定の角度の範囲内で自在に回動が可能な構造と作業内容に応じて作業機17を交換できる構造を有する。この構造により、動力を使用せず、アーム部14の軽量化を図り、軽貨物車両に積載可能にするとともに低価格化した。【選択図】図1
